// Uses pre allocated lockfree queue for maximum throughput even under large

// number of threads.

// Fast asynchronous logger.

// Uses pre allocated queue.

// Creates a single back thread to pop messages from the queue and log them.

//

// Upon each log write the logger:

//    1. Checks if its log level is enough to log the message

//    2. Push a new copy of the message to a queue (or block the caller until

//    space is available in the queue)

//    3. will throw spdlog_ex upon log exceptions

// Upon destruction, logs all remaining messages in the queue before

// destructing..
